摘要
Background Outcomes in patients requiring coronary artery bypass graft （CABG） surgery have been improved with devices such as the intra-aortic balloon pump （IABP）.Good coronary collateral circulation （CCC） has been shown to reduce mortality in patients with coronary artery disease （CAD）.We aimed to investigate whether poor preoperative CCC grade is a predictor of in-hospital mortality in CABG surgery requiring IABP support.Methods Fifty-five consecutive patients who were undergoing isolated first time on-pump CABG surgery with IABP support were enrolled into this study and CCC of those patients was evaluated.Results Twenty-seven patients had poor CCC and 28 patients had good CCC.In-hospital mortality rate in poor CCC group was significantly higher than good CCC group （14 （50％） vs.4 （13％）,P=0.013）.Preoperative hemoglobin level （OR：0.752; 95％ CI,0.571-0.991,P=0.043）,chronic obstructive pulmonary disease （OR：6.731; 95％ CI,1.159-39.085,P=0.034） and poor CCC grade （OR：5.750; 95％ CI,1.575-20.986,P=0.008） were associated with post-CABG in-hospital mortality.Poor CCC grade （OR：4.853; 95％ CI,1.124-20.952,P=0.034） and preoperative hemoglobin level （OR：0.624; 95％ CI,0.476-0.954,P=0.026） were independent predictors of in-hospital mortality after CABG.Conclusion Preoperative poor CCC and hemoglobin are predictors of in-hospital mortality after CABG with IABP support.
